But Facebook Timeline or not, the survey found that 75 percent of users on the social network felt unhappy with their current weight, with 51 percent reporting that seeing of pictures of themselves on the site made them more aware of their size. Nearly 1 in 3 users said that when they compared pictures of themselves to pictures of friends, they felt sad.

"Facebook is making it easier for people to spend more time and energy criticizing their own bodies and wishing they looked like someone else," Dr. Harry Brandt, director of The Center for Eating Disorders at Sheppard Pratt, said in a press release. "In this age of modern technology and constant access to SmartPhones and the internet, it's becoming increasingly difficult for people to remove themselves from images and other triggers that promote negative body image, low self-esteem and may ultimately contribute to eating disorders."

Steven Crawford, associate director at the Center for Eating Disorders, said that excessively monitoring one's weight can be a contributing factor to eat disorders, and that behavior is now easier than ever thanks to Facebook.

"People are now constantly aware of their appearance, thanks to Facebook. A common reaction is, 'I need to be thinner' And it's that kind of thinking that can lead to hazardous dieting," Crawford told TechNews Daily.

"Facebook is an influential factor in developing severe eating disorders," he said.

At least one study has linked Facebook use with eating disorders. A survey of 248 female Facebook users age 12-18 found that the more time young women spend on Facebook, the more likely they are to develop an eating disorder.

The results showed that the more time girls spend on Facebook, the more they suffered conditions of bulimia, anorexia, physical dissatisfaction, negative physical self-image, negative approach to eating and more of an urge to be on a weight-loss diet. Extensive online exposure to fashion and music content showed similar tendencies, but manifested in fewer types of eating disorders.
